Question:

Q. I keep setting built-in messaging apps to use my mass memory for their data and they keep switching back. Why do they do this?

Answer:

A. Every time you connect up your phone in PC Suite or Data Transfer/Mass storage mode, your PC 'mounts' your phone's storage disks (E: and F: on an N97 - for example - with mass memory and microSD). This locks them out for phone use, so any running apps will be forced to switch back to disk C: For this reason, it's best to stick to C: for data and try to manage your free space better.
